  1. 21. Hydrogen production from automotive waste via integrated plasma gasification and water gas shift.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marco Occhinero; [2019]
    Nyckelord :;

    Sammanfattning : The growing amount of landfilled waste could pose a problem in many parts of the world due to the scarcity of landfilling space and environmental threats. In particular, automotive shredder residue (ASR) waste, a by-product of the dismantling of End of Life Vehicles (ELVs), has been proven to represent an issue in particular in the EU, where countries are struggling to compel to the directives that regulate this type of waste.

  3. 22. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    Master-uppsats, KTH/Energiteknik

    Författare :Aravind Ganesan; [2019]
    Nyckelord :syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Sammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER

  4. 23. Experimental study of high-pressure fluidized bed gasification of biomass at pilot scale: A proof of concept

    Master-uppsats, KTH/Kemiteknik

    Författare :Ayush Agarwal; [2019]
    Nyckelord :;

    Sammanfattning : Climate change is real. Rising world population and increasing energy demands are taking a toll on the planet. Moving towards a greener, cooler and sustainable future, there is a need for cleaner, efficient, and reliable sources of energy, and biomass is one of them. LÄS MER

  5. 24. Organisational Learning in Business Model Innovation in the Bottom of Pyramid market : An empirical fieldwork about the market introduction of clean cookstoves in Mozambique

    Master-uppsats, Linköpings universitet/Företagsekonomi; Linköpings universitet/Filosofiska fakulteten

    Författare :Stefan Premer; Brenda Nansubuga; [2018]
    Nyckelord :Organisational Learning; Organizational Learning; Knowledge; Knowledge Transfer; Experimental Learning; Experiental Learning; SECI; Tacit; Explicit; External Learning; Internal Learning; Learning from the environment; Business Model; Business Model Innovation; Bottom of Pyramid; Bottom of Pyramid market; BoP; cleantech; clean technology; clean cookstoves; clean cooking; gasification; cashew; cashew nut; cashew nut shells; market introduction; Mozambique; Africa; Sub-Saharan Africa; development; sustainability; climate change; renewable energies; ethnographic studies; fieldwork;

    Sammanfattning : There is a need for cleaner technology initiatives into the Bottom of the Pyramid (BoP) market to combat the effects of climate change. The difficulty of these initiatives lies in their business model innovation process, as those organisations struggle in finding adequate strategies to establish their business in the BoP market.

  7. 25. Värmeöverföring mellan två zoner i en bubblande fluidiserad bädd

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Christian Stigsson; [2018]
    Nyckelord :Heat transfer; fluidized beds; multi-staging; Eulerian-Eulerian two-fluid; Technology and Engineering;

    Sammanfattning : In this Master's thesis, the heat transfer between two zones in a bubbling fluidized bed and the resultant temperature field were examined using a laminar Eulerian-Eulerian two-fluid model in computational fluid dynamics. The purpose was to estimate the thermal potential to multi-stage a combined heat and power boiler by integration therein of a communicating gasification reactor, which utilizes heat from the combustion, and to analyze how different construction parameters influence the homogeneity of the gas temperature field.
